Darren Maddy admitted "it's a young man's game" after playing his final game in the Friends Life T20 on Tuesday night.
Warwickshire's defeat to Somerset at Edgbaston brought to end an illustrious career in the short form of the game - Maddy was the first player in the world to score 1,000 runs in the format and went on to score 2,534 runs at an average of over 30.
The 39-year old won the Twenty20 Cup twice and also played four internationals for England in the inaugural T20 World Cup in 2007.
"I'm very sad I have to say, words can't really describe what I'm feeling," Maddy told Sky Sports following the game.
"It's a young man's game to be honest. The game has evolved, I wouldn't even dream about playing a 'ramp shot'. When I first started it would be completely bonkers to do anything like that, and I still can't do it.
"But I've had a great run and I'm very proud of what I've achieved. Just to be able to finish on a high like this, on a personal high, it means a lot.
"I was very lucky to play in four consecutive finals days with Leicestershire, winning two of them and those are special days. It's a fantastic competition, it brings the crowds in and I think we've seen the development of batters and bowlers.
"Their skill levels have to be much higher than when we first started and the game has evolved, and that's all down to Twenty20 cricket."
